Title:
CIRCUIT FOR IMPROVING CLOCK ACCURACY, AND CLOCK
Document Type and Number:
WIPO Patent Application WO/2022/057953
Kind Code:
A1
Abstract:
Disclosed are a circuit for improving clock accuracy and a clock. The circuit comprises an MCU controller, a temperature sensor, and a humidity sensor. An output end of the temperature sensor is connected to the MCU controller. An output end of the humidity sensor is connected to the MCU controller. The MCU controller has a clock function. Calculation is performed according to currently received temperature data and humidity data, as well as preset temperature data, humidity data, and an error curve so as to correct the clock accuracy. A clock using the present circuit has higher output accuracy, higher stability, higher product metering accuracy, and reduced costs.
